An insulating material prevents the flow of electricity through it. Insulators help to prevent shocks & short circuits, providing electrical insulation as one of the most important components of any building or system.
This also implies that measuring resistance is essential and you must have a thorough understanding of the resistance levels in order to take safe measures.
This test is essential for ensuring the safety of insulating materials prior to high voltage testing.
It is also a periodic test for certain electrical duties.
This test is performed with DC effort, which implies that just the value of resistance (R) will be determined, but the value of the handicap (XL) will be valued zero as there is no hesitation in the DC effort.
Many test devices can be utilized with IR testing, and these devices provide a wide range of voltage that can be employed on electrical missions from 500 V to 5000 V.
This test is applicable to several activities, including
• Voltage adapters,
• Current transformers,
• Electric power adapters, and
• Electrical cables.
